Patients with recurrent cervical cancer have a poor prognosis. Cemiplimab, the fully human programmed cell death 1 (PD-1)–blocking antibody approved to treat lung and skin cancers, has been shown to have preliminary clinical activity in this population. In this phase 3 trial, we enrolled patients who had disease progression after first-line platinum-containing chemotherapy, regardless of their programmed cell death ligand 1 (PD-L1) status. Women were randomly assigned (1:1) to receive cemiplimab (350 mg every 3 weeks) or the investigator’s choice of single-agent chemotherapy. The primary end point was overall survival. Progression-free survival and safety were also assessed. A total of 608 women were enrolled (304 in each group). In the overall trial population, median overall survival was longer in the cemiplimab group than in the chemotherapy group (12.0 months vs. 8.5 months; hazard ratio for death, 0.69; 95% confidence interval [CI], 0.56 to 0.84; two-sided P<0.001). The overall survival benefit was consistent in both histologic subgroups (squamous-cell carcinoma and adenocarcinoma [including adenosquamous carcinoma]). Progression-free survival was also longer in the cemiplimab group than in the chemotherapy group in the overall population (hazard ratio for disease progression or death, 0.75; 95% CI, 0.63 to 0.89; two-sided P<0.001). In the overall population, an objective response occurred in 16.4% (95% CI, 12.5 to 21.1) of the patients in the cemiplimab group, as compared with 6.3% (95% CI, 3.8 to 9.6) in the chemotherapy group. An objective response occurred in 18% (95% CI, 11 to 28) of the cemiplimab-treated patients with PD-L1 expression greater than or equal to 1% and in 11% (95% CI, 4 to 25) of those with PD-L1 expression of less than 1%. Overall, grade 3 or higher adverse events occurred in 45.0% of the patients who received cemiplimab and in 53.4% of those who received chemotherapy. Survival was significantly longer with cemiplimab than with single-agent chemotherapy among patients with recurrent cervical cancer after first-line platinum-containing chemotherapy.

This study aimed to describe the demographic and clinical characteristics of cancer inpatients with COVID-19 exploring clinical outcomes. A retrospective search in the electronic medical records of cancer inpatients admitted to the Brazilian National Cancer Institute from April 30, 2020 to May 26, 2020 granted identification of 181 patients with COVID-19 confirmed by RT-PCR. The mean age was 55.3 years (SD ± 21.1). Comorbidities were present in 110 (60.8%) cases. The most prevalent solid tumors were breast (40 [22.1%]), gastrointestinal (24 [13.3%]), and gynecological (22 [12.2%]). Among hematological malignancies, lymphoma (20 [11%]) and leukemia (10 [5.5%]) predominated. Metastatic disease accounted for 90 (49.7%) cases. In total, 63 (34.8%) had recently received cytotoxic chemotherapy. The most common complications were respiratory failure (70 [38.7%]), septic shock (40 [22.1%]) and acute kidney injury (33 [18.2%]). A total of 60 (33.1%) patients died due to COVID-19 complications. For solid tumors, the COVID-19-specific mortality rate was 37.7% (52 out of 138 patients) and for hematological malignancies, 23.5% (8 out of 34). According to the univariate analysis COVID-19-specific mortality was significantly associated with age over 75 years (P = .002), metastatic cancer (p <0.001), two or more sites of metastases (P < .001), the presence of lung (P < .001) or bone metastases (P = .001), non-curative treatment or best supportive care intent (P < .001), higher C-reactive protein levels (P = .002), admission due to COVID-19 (P = .009), and antibiotics use (P = .02). After multivariate analysis, cases with admission due to symptoms of COVID-19 (P = .027) and with two or more metastatic sites (P < .001) showed a higher risk of COVID-19-specific death. This is the first Brazilian cohort of cancer patients with COVID-19. The rates of complications and COVID-19-specific death were significantly high.

The treatment of advanced gynecologic cancers remains palliative in most of cases. Although systemic treatment has entered into the era of targeted drugs the antitumor efficacies of current therapies are still limited. In this context there is a great need for more active treatment and rationally designed targeted therapies. The PI3K/AKT/mTOR is a signaling pathway in mammal cells that coordinates important cell activities. It has a critical function in the survival, growth, and proliferation of malignant cells and was object of important research in the last two decades. The mTOR pathway emerges as an attractive therapeutic target in cancer because it serves as a convergence point for many growth stimuli and, through its downstream substrates, controls cellular processes that contribute to the initiation and maintenance of cancer. Aberrant PI3K‐dependent signaling occurs frequently in a wide range of tumor types, including endometrial, cervical, and ovarian cancers. The present study reviewed the available evidence regarding the potential impact of some mTOR pathway inhibitors in the treatment of gynecological cancer. Few advances in medical management have occurred in recent years in the treatment of advanced or recurrent gynecological malignancies, and a poor prognosis remains. Rationally designed molecularly targeted therapy is an emerging and important option in this setting; then more investigation in PI3K/AKT/mTOR pathway‐targeted therapies is warranted.

In a phase III, randomised, active-controlled study (EMPOWER-Cervical 1/GOG-3016/ENGOT-cx9; R2810-ONC-1676; NCT03257267) and cemiplimab significantly improved survival versus investigator's choice of chemotherapy among patients with recurrent cervical cancer who had progressed on platinum-based therapy. Here we report patient-reported outcomes in this pivotal study. Patients were randomised 1:1 to open-label cemiplimab (350 mg intravenously every 3 weeks) or investigator's choice of chemotherapy in 6-week cycles. Patients completed the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 during cycles 1-16. Least-squares mean changes from baseline in global health status (GHS)/quality of life (QoL) and physical functioning (PF) were secondary end-points in the statistical hierarchy. Of 608 patients (304/arm), 77.8% patients had squamous cell carcinoma and 22.2% patients had adenocarcinoma. Questionnaire completion rates were ∼90% throughout. In the squamous cell carcinoma population, overall between-group differences statistically significantly favoured cemiplimab in GHS/QoL (8.49; 95% confidence interval [CI]: 3.77-13.21; P = 0.0003) and PF (8.35; 95% CI: 4.08-12.62; P < 0.0001). Treatment differences favoured cemiplimab in both histologic populations by cycle 2. Overall changes from baseline in most functioning and symptom scales favoured cemiplimab, with clinically meaningful treatment differences in role functioning, appetite loss and pain in both populations. The sensitivity analyses, responder analyses and time to definitive deterioration favoured cemiplimab in both populations. Cemiplimab conferred favourable differences in GHS/QoL and PF compared with chemotherapy among patients with recurrent cervical cancer, with benefits in PF by cycle 2, and clinically meaningful differences favouring cemiplimab in role functioning, appetite loss, and pain.
